In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 6800 Ultra are very slightly better than the Nvidia GeForce 8600 GS.

The GeForce 8600 GS was released over a year more recently than the GeForce 6800 Ultra, and so the GeForce 8600 GS is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 6800 Ultra.

The GeForce 8600 GS and the GeForce 6800 Ultra have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce 6800 Ultra has 22.4 GB/sec greater memory bandwidth than the GeForce 8600 GS, which means that the memory performance of the GeForce 6800 Ultra is slightly better than the GeForce 8600 GS.

The GeForce 8600 GS has 16 Shader Processing Units and the GeForce 6800 Ultra has 22. However, the actual shader performance of the GeForce 8600 GS is 22 and the actual shader performance of the GeForce 6800 Ultra is 9. The GeForce 8600 GS having 13 better shader performance is not particularly notable, as altogether the GeForce 6800 Ultra performs better when taking into account other relevant data.

The GeForce 8600 GS requires 47 Watts to run and the GeForce 6800 Ultra requires 124 Watts. We would recommend a PSU with at least 350 Watts for the GeForce 8600 GS. The GeForce 6800 Ultra requires 77 Watts more than the GeForce 8600 GS to run. The difference is significant enough that the GeForce 6800 Ultra may have an adverse affect on your yearly electricity bills in comparison to the GeForce 8600 GS.

GPU Mini Review

Mini ReviewGeForce 8600 GS is a middle-class GFX based on the 80nm variant of the first-shader unified architecture.
It's based on the G84 Core and offers 16 Shader Processing Units, 8 TMUs and 8 ROPs, on a 128-bit memory interface of DDR2. The central unit runs at 540MHz and the memory clock operates at 400MHz. It will consume no more than 47 Watt.
It's therefore more comparable to GeForce 8500 GT and pales in comparison with GeForce 8600 GT.
This GPU is only suited for a 1024x768 (or less) resolution. Most of today's games will only run at low settings and extremely demanding games might not run at all. DirectX 11 based games aren't supported and its performance will decrease drastically, as the resolution increases.
The groundbreaking new NVIDIA GeForce 6800 graphics processing units (GPUs) and their revolutionary technologies power worlds where reality and fantasy meet; worlds in which new standards are set for visual realism and quality, performance, and video functionality. The GeForce 6800 GPUs deliver powerful, elegant graphics to drench your senses, immersing you in unparalleled worlds of visual effects for the ultimate PC experience.
